WAEC SSCE - Chemistry - 2008 (Objective)

Question 1 Report

In a fixed volume of a gas, an increase in temperature results in an increase in pressure due to an increase in the

number of the collisions between the gas molecules and the walls of the container

kinetic energy of the gas

number of collisions between the gas molecules

number of repulsion between the gas molecules

Answer Details

When the temperature of a gas is increased, the kinetic energy of the gas molecules increases. This means that the gas molecules move around faster and collide with the walls of the container more frequently and with greater force. This increase in the frequency and force of the collisions between the gas molecules and the walls of the container results in an increase in pressure. Therefore, an increase in temperature of a gas in a fixed volume results in an increase in pressure due to an increase in the number of collisions between the gas molecules and the walls of the container.
